A fixed frame 572 is fixedly connected to the lower portion of the workbench 1, the fixed frame 572 is arranged in a concave shape, the fixed frame 572 is located between two clamping arms 571, a telescopic cylinder 573 is bolted to the bottom of the fixed frame 572, a piston rod of the telescopic cylinder 573 penetrates through the fixed frame 572 and is connected with a column head 574, pull wires 575 are tied to the arm bodies of the two clamping arms 571 located above the workbench 1, and the pull wires 575 slide from the workbench 1 and are tied to the column head 574.

When a worker places the volute body 02 in place, the piston rod of the telescopic cylinder 573 retracts, so that the pull wire 575 is pulled through the column head 574, the pull wire 575 pulls the clamping arm 571 to rotate, and therefore the two clamping arms 571 are matched with the flange 05 for clamping the volute body 02.

In addition, a return tension spring 576 is hung between the arm body of each of the two clamping arms 571 below the workbench 1 and the fixing frame 572, so that when the piston rod of the telescopic cylinder 573 extends, the return tension spring 576 can push the clamping arms 571 to rotate in the opposite direction, the clamping arms 571 are separated from contact with the flange 05, and a worker can take the volute body 02 conveniently.

The implementation principle of the embodiment 2 is as follows: when a worker places the volute body 02 in place, the piston rod of the telescopic cylinder 573 retracts, so that the pull wire 575 is pulled through the stud 574, the pull wire 575 pulls the clamping arm 571 to rotate, and thus the two clamping arms 571 are matched with the flange 05 for clamping the volute body 02. When the piston rod of the telescopic cylinder 573 is extended, the worker can pull the flange 05 of the volute body 02 out from between the two holding arms 571.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
